MEANS FOR TRANSMITTING MOTION.

:TJPECIFIGATIQN forming part of Letters Patent No. 332,692, datedDecember 15, 1885.

Application filed June 11, 1895. Serial No. 168,937. (No model.)

To all whom it may concern Be it known that I, HUGH WRIGHT, a citizen ofthe United States, residing at New Lisbon, in the county of Oolumbianaand State of Ohio, have invented certain new and useful Improvements inMeans for TransmittingMotion; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to means for transmitting motion from one shaft toanother, and for the purpose of illustration I have shown it applied toa circular-saw mill in which two saws are used, the smaller one mountedabove the larger.

The object of the invention is to provide a simple and efficient meansfor connecting and disconnecting two shafts and transmitting power fromone shaft revolving in a given direction to another shaft, and causingit to revolve in the same direction.

My invention consists in the combination of devices hereinafterdescribed,and particularly pointed out in the claims.

In the accompanying drawings, which form part of this specification,Figure 1 is an end elevation of a saw-mill embodying my invention. Fig.2 is a vertical section. Fig. 3 isa side view of one of the brackets,showing the pivoted hanger attached thereto. Figs. 4 and 5 are detailviews.

Reference being had to the accompanying drawings, A represents the frameof the saw, which is constructed of cast-iron. B represents the main sawsecured upon the main shaft 0 in the usualmanner. Upontheframe A aresecured two vertical brackets, D D, on which are arranged adjustablejournals E, constructed in one piece, forming an integral part of thehanger T, for carrying the secondary or supplemental shaft F of the sawG, which saw is provided with a driving-pulley, H. To the bracket D ispivoted at I a hanger, J, in the end of which is journaled a shaft, K,upon which are mounted pulleys L M. Over the pulleys H M is placed abelt (not shown) for transmitting motion from the shaft 0 to shaft F andsaw G. To the hanger I is attached an arm, N, which is provided with aslot, a, by

which it is connected to lever Q. P represents a bracket secured to theframe A, and is provided with a slot, 1), through which a bolt, 0,attached to the lever Q passes. A stud, d, working in the slot a of thearm N, connects the lever Q with said arm. The main driv ing-pulley P isprovided with projecting flanges e f on each side of the central web, 9.The inner flange, f, ineloses the friction-pulley L, and forms africtional surface, against which the pulley is brought to bear.

\Vhen it is desired to put the upper saw in motion at the same time themain saw is at work, the operator seizes the lever Q and moves it in thedirection indicated by the arrow in Fig. 3,which communicates motion tothe swinging hanger I, and causes the pulley L to be brought in contactwith the inner surface of the rim f of the pulley P, which will transmitthe motion of the shaft- 0 to the belt-pulleys M H, shaft F, and saw Gthrough the medium of a belt (not shown) which works upon the pulleys HM. The eccentric connection of the lever Q with the arm N locks thepulley M in either of its extreme positions, whether in or out ofcontact with the rim of the driving-pulley, and therefore requires nofurther attention from the operator after the pulley has been moved intoeither position until it is desired to move it positively.

The shaft F and its journals are adjustable upon the uprights orbrackets D D, and are secured in position by means of set-screws R,passing through yokes S, attached to the hanger T,which supports thejournals E and the shaft F. One of said yokes and its set-screw areclearly shown in Fig. 3 of the drawings.

Upon the main shaft 0 are differential pulleys h t'j. To the under sideof the frame A is attached a swinging frame, A, (shown in Figs. 1, 2,and 5,) which swinging frame is provided with double pivot-points ateach end, (marked at 0.) (Shown in Fig. 5.) By this an rangement of thedouble pivot-points n 0 for the swinging frame A, it is adapted foreither a right or left handed mill. On a supplemental shaft, B,supported by the swinging frame, is mounted a differential pulley, U,having three frictional surfaces, k, Z, and m, for giving differentrates of speed to the sprocket-wheel O and the chain E, whichcommunicates mo tion to the feedrack of the mill. (Not shown.) Thedifferential pulleyis moved longitudinally on the shaft A by means of ashifting-lever, 19. To the pivoted frame is attached a lever, g, bymeans of which said frame can be elevated, bringing the differentfriction-surfaces of the pulley U into contact with the pulleys h 6 asmay be desired.

The swinging frame is moved into the position shown in Fig. 4 in dottedlines by lifting the lever q, thereby bringing the periphery of thepulley r on the shaft 13 into contact with the inner surface of therimfof the driving-pulley P, (see Fig. 2,) thereby obtaining a reversemotion of the feed mechanism of the saw.

The swinging frame A is elevated by pressing down on the lever (1,thereby bringing the differential pulley U against the pulleys h z j,for the purpose hereinbefore stated.

It will be observed thatby the construction shown the motion of the mainshaft 0 is transmitted through its main driving-pulley 1? to the shaftsB and F, by bringing the pulleys L and r to bear against the innersurface of the fiangef of said pulley P.

In another application filed herewith, Serial No. 168,919, I haveclaimed the feed mechanism shown for operating a saw-mill carriage, bothof the present applications being divisions of my application No.115,899, filed December 29, 1888, under requirement of the PatentOffice.

Having thus fully described my invention, what I claim is 1. Thecombination of a main shaft and its driving-pulley, provided with africtional surface, as shown, a secondary shaft, a swinging hangercarrying a belt-pulley and a friction-. pulley, and a lever foroperating the swinging hanger to bring the friction-pulley into contactwith the driving-pulley, substantially as described.

2. The combination of a main driving-pulley,provided with frictionalsurfaces, as shown, a swinging hanger supporting a friction and a beltpulley, and an operating-lever eccentrically connected to the hanger,and a bracket driving-pulley, a secondary shaft adjustably supportedupon brackets, and pulleys, substantially as shown, a swinging hangersupporting a friction-pulley, and an operatinglever, as and for thepurpose set forth.

5. The combination of a main shaft and its driving-pulley, provided withan inner frictional surface,and two friction-pulleys bearing upon themain pulley, and adapted, through means substantially as described, totransmit motion from the main shaft to two supplemental shafts, as andforthe purpose set forth.

6. The combination of driving-pulley provided with frictional surfaces,as shown, a supplemental shaft supported inaswinging frame and carryinga friction-pulley, a lever for operating said frame, a swinginghangerand its pulleys, a lever for operating said hanger, and anadditional shaft driven from the main pulley, substantially as shown anddescribed.

7. The combination of pulley P, provided with inner frictional surface,laterally-swinging hanger J, supporting pulleys L M, shaft F, pulley H,and lever Q, substantially as described.

8. The combination of pulley P, shafts B andF, swinging hangerJ,friction-pulleys L0, belt-pulleys M H, swinging frame A, andopcrating-levers Q and q, substantially as de scribed. I

In testimony whereof I affiX my signature in presence of two witnesses.
